Software-Raid

I had some problems with mdadm in the past and Btrfs seems to be a good alternative for it. I will remove one disk of my mdadm-array and turn it into btrfs. Then I will copy all my data on my btrfs using Compression. Of course I will backup my data. Then I will remove my mdadm-array and add the hard-disk to my btrfs, convert the filesystem to a Raid1 and create a Subvolume on it for all my /home-directories. I am courious how it works...

Software-Raid can be a pain in the a**. What if a disk has some kind of temporary failure, jumps out of it's raid-array and creates is own raid-array(all the raid-informations are stored on the disk)? That's bad, because then we have 2 raid-arrays with the same data(raid-fork). If we also use LVM2 things start to get really bad. Because then it might happen, that the "wrong" raid-array is automatically used at boot-time...
